The LMV321IDCKR is a low-voltage, dual-channel single supply, micro-power CMOS comparator from Texas Instruments. It is designed to operate in a range of 1.1V to 5.5V, and has an input common-mode voltage range of 0.2V below the negative supply power (VSS) to AVDD + 0.8V. It features a wide gain bandwidth product of 8MHz, and low quiescent power (less than 0.1µA). It has a fast enable/disable response time, TTL compatible enable/disable functions, a single supply architecture, as well as adjustable hysteresis. The LMV321IDCKR is ideal for portable, automotive, and industrial applications.
